Fifi, who has suffered with the condition for years, said the loss had hit her “full whack”.

She spoke out after the suicide of actor Robin Williams this week.

And she has revealed the “misery” hanging over her every day since Peaches died in April aged 25.

Writing on her Instagram page, she said: “I wear a permanent mask so I won’t be judged for feeling how I actually feel.

“You can’t escape it, it just simmers under the surface when it’s not hitting you full whack.

“Which, for obvious reasons, it has done to me for the last few months.

“People wouldn’t have the first clue of it to look at me or talk to me, though.”

It comes just weeks after an inquest found mum-of-two Peaches died as a result of a heroin overdose. The TV presenter was found on a bed surrounded by drugs paraphernalia.

PR executive Fifi, 31, has been a staunch defender of her sister since the tragic event.

She has hit out at web trolls and blasted them for “buying into the bulls***”.

But she has found it harder to cope after Williams’s death this week.

She posted a picture of the Hollywood legend with his words: “You’re only given one little spark of madness. You mustn’t lose it.”

And she wrote: “Devastated by the news. Depression needs to be taken a lot more seriously.

“No-one should feel pushed to those actions by their all-encompassing misery.

“Makes me so sad that he had the world crying with laughter whilst drowning in his own tears.

“His films have been a constant in my life, from childhood giggles with Hook and Mrs Doubtfire. To drawing out the deeper emotions in later life with Good Will Hunting and my favourite of his, Dead Poets Society.

“A unique one of a kind who will be truly missed. RIP Mr Williams.

“I think this has prompted me to want to speak out publicly about my own depression which I’ve suffered from for years.
